I installed Warp 3, 4 and 4.52 as VM under Virtualbox 7.0.4 in Arch-Linux.
All 3 work per se, even with 1600x1200 SVGA.
Under Warp 3 everything else I tried works too (also with SMP), e.g. emx-0.9d.
Under Warp 4 and 4.52, calling unzip results in an unresponsive DOS-window or SYS3170 for all unzip versions I tried (32-bit and 16-bit).
The same is true for some other utilities I've tested.
Warpin-1-0-26 yields "SYS1057 - file or pathname invalid in a DOS session",
when called from an OS2 window. Double-click in PM on warpin pops up a
window for a fraction of a second.
I tried many virtualization options (nested paging on/off,
PAE/NX on/off, Standard/KVM/Hyper, 1-4 CPU's ...): always the same result.
I compared the Config.sys of 3, 4 and 4.52 and found nothing unusual.
I can't install unzip, hence no zipped utilities. All self-extracting exe's that I tried return SYS3170.
Taking unzip552 as an example for the unzip's tried:
- 32-bit unzip.exe results an unresponsive DOS-window
- 32-bit funzip.exe yields SYS3170 (screenshot attached), same for 16-bit exe's.
What surprises me is that under the older Warp 3 everything works (in the case
of jm Graphics for emx only the PM window works (VESADLL=VESA_PM), but still).
Can someone explain to me what's going on?
